Samsung patents 5G method to pause and restart secondary network connections

This patent describes a method for 5G devices to manage dual connectivity by pausing a secondary network link to save power. When the link is paused, the device resets certain internal timers but keeps one specific timer active. To restart the link, the device checks if that timer is still running; if not, it performs a standard reconnection process.

Why it mattersThis improves battery life and connection stability for 5G phones by efficiently managing how they switch between primary and secondary network signals.

In the filing’s own words

The present disclosure relates to a communication method and system for converging a 5 th -Generation (5G) communication system for supporting higher data rates beyond a 4 th -Generation (4G) system with a technology for Internet of Things (IoT). The present disclosure may be applied to intelligent services based on the 5G communication technology and the IoT-related technology. A method performed by a terminal in a wireless communication system is provided. The method comprises receiving, from a first base station associated with a master cell group (MCG), a first radio resource control (RRC) message including a second RRC message generated by a second base station associated with a secondary cell group (SCG), identifying first information indicating a deactivation of the SCG included in the second RRC message, and determining to deactivate the SCG based on the first information indicating the deactivation of the SCG.

What exactly they claim (claim 1)

1. A method performed by a terminal in a wireless communication system, the method comprising: receiving, from a base station, a first radio resource control (RRC) message indicating that a secondary cell group (SCG) is in a deactivated state; deactivating the SCG and resetting a medium access control (MAC) entity for the SCG based on the first RRC message, wherein the resetting of the MAC entity comprises stopping at least one timer in the MAC entity except a time alignment timer; receiving, from the base station, a second RRC message indicating that the SCG is in an activated state; based on the SCG being indicated in the activated state, identifying whether the time alignment timer is running; and based on identifying that the time alignment timer is not running, performing a random access procedure for SCG activation.
